Ever since I've owned the car (about a year & a half) I noticed the right rear tire sits 1-1/4" further to the rear than the left rear tire. The car never seemd to mistrack while driving so i didn't pay much attention to it.

It's bugging me now so I'm gonna get both rear wheels sitting right. Any tips on what I should be looking for? The rear is all stock. I heard I can align them with adjustible LCA's.

 

What you need is an adjustable panhard bar, to center the wheels left-to-right. But then you're going to need an alignment, too.

 

He said alignment front to rear, not side to side.

 

If you take it to an alignment shop, that does a 4 wheel alignment, they should be able to tell you how for forward/back the wheel is.....

Thats how I found out my right side was off 1/4" ..... MY stock LCA was bent....

 

Went to UMI's site, looking at their LCA's. Got to thinking, do I really NEED adjustible LCA's or will their solid ones be just as good? Since they are the same length I'm assuming this should theoretically align the rear axle.
Not familiar with rear ends so bear with me when I ask, what factors in a rear end setup would require adjustible LCA's? If I understand them correctly, rather than for rear axle alignment, they help keep the rear tires planted to the pavement. SO the adjustible LCA's allow you to increase the force being applied to the read axles helping to keep them planted even stronger?

 

The aftermarket LCA's have firmer bushings, and are structurally more rigid. Less flex, controlling the stability of the axle, as it tries to push the car forward, using the LCA's. Also reduces the up-and-down displacement of the factory bushing, which have "hollows" at the top and the bottom. Should reduce wheel hop. But the firmer bushings may lead to suspension bind when cornering hard, and the body starts to roll. In that case, you might want a softer bushing or a spherical rod end on one end of the LCA.

Adjustables could be used to compensate for damaged mounting brackets, on the body end or the axle end, but that would just be a band-aid, rather than fixing the real problem. Adjusting both sides allows you to move the axle forward or backward in the wheel openings, to adjust clearance for running large slicks. I moved the rear axle back about a 1/4" to keep the 28x11.5-15 QTP's from hitting the front edge of the wheel opening, as they started to grow when trap speeds approached 130MPH.

You should inspect your LCA's and the mounting points, to see if the LCA's are still straight, and the brackets are not bent. Also check the rear axle housing to make sure it isn't bent. It would take an awful lot of damage to displace one wheel 1.25" behind the other.

 

Supprised no one else noticed this. If there is "no mistrack" I'd be at the body shop tomorrow having them check for damage.

 

Update: I put the car on ramps and took my time taking a close look at everything. No apparent damage or warpage of the LCAs and the mounting brackets. I measured both LCAs and they are identical lengths. I looked at the rear axle...no damage of any sort.

Only thing I did notice is that the passenger side of the axle DOES sit back further than the driver side. This is clearly visible if you get under it and see how it sits under the rubber bump stops. Nothing looks damaged or twisted in any way, other than it sitting off.

I looked closely at the body and even took measurements...body seems good. I measured the depth of the tires from the outer edge of the fenders and there is maybe a 1/4" difference if that...passenger side sticks out just a bit further.
